ViewPreparer issue after updating from 6.2.0 to 6.3.0.1

[Chris Scroll <ch...@gmail.com>]

After I updated to struts 6.3.0.1 I am receiving the following exception:

java.lang.ClassCastException: helpers.preparer.BreadCrumbPreparer cannot be
cast to org.apache.tiles.api.preparer.ViewPreparer

If I revert back to struts2-tiles-plugin-6.2.0.jar the program runs without
exceptions.

Note: My BreadCrumbPreparer class implements 'ViewPreparer' from
tiles-api-3.0.8.jar

Could you post the whole stack? As far as I see the ViewPreparer
interface [1] is part of the plugin, maybe we have both JARs on
classpath - tiles-api & struts2-tiles-plugin?
